WEST SUSSEX, U.K. - s4story -- Cryolab, a specialist supplier of cryogenic equipment, consumables and servicing to laboratories worldwide, has published a practical guide to storage in tissue banks.

The guide is written for tissue bank managers, quality leads and laboratory staff who plan or run a storage facility. It explains that a tissue bank runs several cold chains at once, and that only cryopreserved, viable tissue needs liquid nitrogen.

Topics covered include:

- Storage classes by preservation method, from freeze-dried tissue at room temperature to deep frozen bone and tendon at -40 °C or colder
- Cryopreserved tissue such as heart valves, held at -100 °C or colder under the AATB standard and usually below -135 °C in nitrogen vapour
- Separate storage for quarantined, released and rejected tissue, as required in the UK by Human Tissue Authority guidance
